To all whom t may concern: y

Be it known that l, CLAYTON O. 'Wnirn, a citizen of the United States,and resident of the city of Seattle, county of King, and State ofWashington, .have invented certain new and useful Improvements inHeadlights, of which the following is a specication.

rllhis invention relates to new and useful improvements inheadlights,and more. par- 3-0 ticularly to headlightsof that character especiallyuseful on motor vehicles the principal object of the invention being toprovide a combination which embodies features of the usual automobilespot light and antiglare headlight ,whereby a central shaft of light ofeffective intensity may be projected directly forward of the light, andwhereby other rays may be projected in a less intensified beam that willsubstantially light 23 up a roadway forwardly of a vehicle eguipped withthe light but will produce no g aring eiect outside of the spot lightbeam, and other rays will be reflected laterally to both sides of theroadway.

35 ln accomplishing this and other objects of the invention, l haveprovided' the improved details of construction, the preferred forms ofwhich are illustrated in the accompanying drawings, wherein-- Figure lis a central sectional view of a headlight constructed according to thepresent invention.

F igure 2 is a front view of the saine.

Fi ure 3 is a transverse, sectional view on the line 3--3 of Figure l.

Referring more in detail to' the several viewsv of thedrawings, whereinlike reference numerals designate like parts--the numeral l designates areflector body, which 40 may be made in any desirable or suitable sizeand of any desirable'material suitable to its particular use, and whichconsists of a short cylindrical portion 2 which, at its forward edge isturned to form a peripheral l5 flange 3 and continues at its oppositeend into a truncated, conical portion 4 which terminates in a.sphericall curved end section 5; the center aboutw ich the sphericalreflecting surface is formed being in "the axial line of the conical andcylindrical refleeting surface.

Forwardly of the reflecting surface 5 is an electric lamp 6 which ma bemounted and adjutsed in any of the we l known ways now employed, andelectrically connected with circuit wires for supplying electricitythereto.

The intermediate, or conical portion 4 of the reflector body has ribs orridges, 7, formed therein which extend in the general axial direction ofthe cone at regular distances apart with the body portion-con cavedtransversely between the ribs,` as isv particularly illustrated inFigure 3, forniing depressions 8 intermedial the ribs which entendthe'length of the conical portion.

A housing 9 is formed to 4receive the rewith an inturned flange at itsopen end against which the flange 3 may seat. Also a ring member l0 isapplied to these parts to hold them functionally together and alsosecure a glass plate or lens l1 at the front of the housing as isordinarily d one.

ln using a headlight of this character, the lamp 6 is located in, oradjusted to such position, that the best results will be gained from thespot light reiecting surface; that is, so that it will cast a narrow andintense shaft of light directly forward of the re Hector.

It is apparent also that the shaft of light produced or thrown out bythe spherical or 'spot lightreflecting surfaceq will be surrounded by amuch less intense light reflected from the ribbed conical reectingsurface 4, which, being so ribbed, will effectively diffuse all lightrays reflected therefrom that no undesirable glaring eifect is producedand a roadway forward of a Vehicle,

flector body, and this preferablyis provided equipped with such a lightwill be plainly visible.

It is also noted that the cylindrical reflecting surfaces 2 will causeother rays of light to be cast laterally of the direction of light fromthe other surfaces and will serve to illuminate objects adjacentopposite sides of the roadway. i

It is to be understood that the extent of the spherical and cylindricalreiecting surfaces and conical surface Ilv are subject to modificationand I .do not Wish to be limited Having thus: described my invention,what l claim as new and desire to protect by -Letters Patent, is: y

ln a headlight, .in combination, a reilector body comprising a truncatedconical redecto the'exact form asillustrated.

tor surface 1n terminating at. the smaer end a Spherlcally eurvedrefecmgsuface formed abou; a cener whxch hes 1n the axial -'ine of the eonieaporion, and at s end extended into a cylindrical.

reflecting surface; said eonea bodyI prion having ges extendingongltudnaly thereof nd conceived nntwardlv between said ridges, Wardlyof the spherical relecting surface:

and in the axial line of the Cone.
